COVER OR SIGHT-GUARD FOR FIREARMS.

SPECIFICATION formingpart of Letters Patent No. 660,361. dated October 23, 1900. Application filed February 17, 1900. Serial No. 5,561. (No model.)

To (ZZZ whom it may concern:

Be it known that I, CHRISTIAN CANDRIAN, a

citizen of the United States of America, and

a resident of Springfield, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Covers or Sight- Guards for Firearms, of which the following is a full, clear,

improvement is to devise a protector device which may be most readily engaged with the portion of the rifle-barrel at which the sight is provided and which-when in place thereon is retained with a most firm and secure engagement, whereby the sight-cover may have no movement of displacement either laterally or longitudinally in either direction.

Another object of the invention is the production of a sight-cover from a single struckup blank of thin metal, whereby the device may be most practically and cheaply constructed with all due regard to its fitness to purpose and effioiency; and the invention consists in the sight-cover having the structural features and capabilities hereinafter described; and it also consists in the sight-cover composed of a sheet-metal blank of particular form having portions thereof bent and coacting one with another, as hereinafter de-,

scribed, and set forth in the claims.

Reference is to be had to the accompanying drawings, in which this invention is illustrated, wherein Figure 1 is a perspective view of the improved sight-cover shown as applied on the muzzle end of a rifle-barrel. Fig. 2 is a front end elevation of Fig. 1. Fig. 3 is a side elevation of a portion of the gun-barrel and sight, the sight-cover being shown in longitudinal vertical section as taken on the line 3 3, Fig. 2. view as taken on the line 4 4, Fig. 2.

Fig. 4 is a horizontal sectional Fig. 5

is a plan view of the sheet-metal blank from which the sight-cover is composed.

In the drawings, A represents the rifle-barrel, having at the muzzle end thereof the upstanding stud or base at for the sight I). The

' upper portion of the sight-base is of rectangular form.

' B represents the sight-cover, the same comprising the approximately-tubular longitudinally-ranging hood portion d, having at opposite sides the downwardlycontiuuing portions ff, ranging longitudinally in parallelism and terminating in the arc-shaped spring members or clips 9 g, which are adapted to be sprung over and into engagement with and to embrace somewhat more than half of the cir' cumference of the barrel next below the sightbase. The rear side or check member f, which is intermediate between the hood and one of the spring-clips, has a lug or extension h, which projects across to the front side of the front cheekf and is provided with the lip i, which is again turned at right angles to have its position in proximity alongside the front face of said front cheek, and the front cheek memberfalso similarly has a duplicate extension-lug, which projects across to the rear side of the rear cheek and is provided with the lip i, which is turned at right angles to have its position inproximity alongside the rear face of the rear cheek. One of the extensions h is formed integrally and extended from the front edge portion of the cheek, while the other extension is formed integrally with and extended from the rear edge of the other cheek.

When the cover is snapped into place, the clip members thereof embracing the gun-barrel, the cheek members fit about the opposite sides of the upper portion of the sight-base, while the aforesaid cross extensions h it have their positions alongside and practically in contact against the front and rear ends of the sight-base.

When the device is being sprung into its constrictive engagement by the clip portions g 9 about the barrel, the said clips, together with the cheek portions f f, are deflected outwardly from the points 00 w of junction of the cheeks with the approximately-tubular hood or guard d; but before the clips will have ioo ' spread sufficiently open to permitthcbottom edges of thelcli psato pass the portionofthe barrel at its greatest diameter the cheeks will have come to a limiting contact against the lips i, so that thereafter a spring reaction of increased intensity is developed and maintained, because of the then shorterlength of the portions of the device which can be capable of further springinge-that-is, the; portions which are below the points y y, Fig. 2.

B represents in Fig. 5 the blank from which the entire.deviceisconstructed-, thesame,co m,- prising the substantially-rectangular middle part d which constitutes when bent into the partially-cylindrical form the hood d, the endwiseecontinued portions f 'f for the checks,

the terminal portions g g for= the clips, and

theopposite side extensions from the pertions f which are indicated at hi, for the I transverse extensions 7b of the device, and the limiting lips or lugs 1 00 00 represent the bending-lines at the junction of the cheekswith: the hood, and w 10 represent the bending-line at the junction of the cheeks and the clips," while 2 z repreportions with which they are integrally formed, and .2 2 represent the bending-lines where the lips or lugs h are turned to have their positionson the faces of the cheeksopposite which these parts areintegrallyformed.

jj represent kerfs or saw-cuts, so that' the parts k 72 may be properly bent at a right angle with the portions which constitute the checks, which portions f as shown by full lines in Fig. 5, are somewhat narrower than the. length of the. hood d; but the portions of the blank outside of thedotted lines o 0) may be omitted, at which the overhanging or hook-like end portions of the hood (indicated atim) would be absent from the sightcover, which would be considered advantageous, wherethe device was to beused on a carbine; but for ordinary military rifles a comparatively long hood is preferred, asprovided for by the comparatively wide middle .portiori' of the blank, as shown.

A most desirable characteristic of this device. for an improvedsight-cover is found to cons-isttin the tenacity with which the device retains its immovable position when placed upon the gun and which is in large degree due to the provision of the transverse exten- ,sions from each cheek across to the opposite one and the right-angularly-turned limiting lips or lugs 'i. The engagement with both the. curved sides" of the barrel and the sides of the sight-base prevent any lateral derangement or displacement from alinemcnt, while ;th.e. transverse portionsh 7t preventany dragging of the device endwise from the barrel, as' miglirtoccurin carrying the gun through brush or undergrowth, or, on the other hand, Eany rearward displacement, as'might occur should the sight-cover strike by its forward Eend against any object.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

l. A sight cover or protectorfor firearms consisting of the approximately-tubulartop portion or hood having the downward continuation constituting the opposite side cheeks ff, and the arcformed spring-clips vg g, and having the extensions h h, integrally formed as portions of thefrontand rear edges of the said cheeks f, extending right-angularly to said cheeks each crosswise from the one toward the other, substantiallyas described.

2. A sight-cover for firearms, consisting of the approximately-tubular top portion or hood, thelower portions of which are downward-1y continued in the opposite parallel cheekshaving therebelow the outwardlycurving-cli'ps-g g and each cheek having at its endthe right-angularly-turned and crosswise extension h having the right-angularlyturned lip or log arranged for' a limiting engagement on the outer face of the cheek opposite that from which the extension is projected, substantially as and for the purposes set forth.
